<title>Problem 1118. -- [POI2009]Prz -- 衡阳八中OJ离线版-2012-02-29</title><center><h2>1118: [POI2009]Prz</h2><span class=green>Time Limit: </span>30 Sec&nbsp;&nbsp;<span class=green>Memory Limit: </span>162 MB<br><span class=green>Submit: </span>73&nbsp;&nbsp;<span class=green>Solved: </span>25<br>[<a href='submitpage.php?id=1118'>Submit</a>][<a href='problemstatus.php?id=1118'>Status</a>][<a href='bbs.php?id=1118'>Discuss</a>]</center><h2>Description</h2><div class=content>你的任务是计算一个函数F(x, y)，其中x和y是两个正整数序列。F的定义如下：

boolean F(x, y)

   if W(x) ≠ W(y) then return 0

   else if |W(x)| = |W(y)| = 1 then return 1

   else return F(p(x), p(y)) AND F(s(x), s(y)).

 

W(x)表示序列x中元素的集合。（元素的顺序和出现次数将被无视）

p(x)表示序列x的最长前缀，满足：W(x) ≠ W(p(x))

s(x)表示序列x的最长后缀。满足：W(x) ≠ W(s(x))

|Z|表示集合Z中元素个数

 

</div><h2>Input</h2><div class=content>第一行k表示数据组数。
对于每组数据，第一行n,m分别表示x序列的长度与y序列的长度，第二行n个数表示xi，第三行m个数表示yi
1<=k<=13
1<=n,m<=100000
1<=xi,yi<=100


</div><h2>Output</h2><div class=content>k行，对于每组数据，若F(x,y)为真输出1，否则输出0。
